Furthermore, a hot air blowing port 45 is provided above the rinsing tank 3, and a hot air pipe 46 communicating with the hot air blowing port 45 is connected to a hot air blower 48 via a hot air generator 47 to blow hot air into the rinsing tank 3. It is like this.

A hot air drain pipe 50 having a drain valve 49 is provided on the hot air pipe 46 and communicates with the waste water pipe 23. Reference numeral 51 in FIG. 2 is a lid of the rinsing tank 3, 5 in FIG.
2 is an operation panel, and 53 is an ultrasonic oscillator.

This embodiment is constructed as described above,
First, the cleaning basket 5 accommodating the object to be cleaned is placed on the lifting table 6 in the cleaning tank 2, and the start switch (not shown) for ultrasonic cleaning on the operation panel 52 is turned “ON” to open the valve 12. The cleaning liquid is opened to supply the cleaning liquid from the mixing tank 14 into the ultrasonic cleaning tank 2, the ultrasonic oscillator 53 is operated, the ultrasonic vibrator 4 is vibrated, and the cleaning is performed by ultrasonic cavitation. Lifting platform 6 by mechanism 8
Move up and down at / 4 wavelength for more uniform ultrasonic cleaning.

A new cleaning liquid is constantly supplied,
The waste liquid overflowed from the overflow hole 24 is discarded from the waste liquid pipe 23. Also, during cleaning, the ozone liquid generation lamps 27, 27 are turned on as needed to generate ozone and sterilize. After a lapse of a predetermined time, the switch is turned "OFF", and the cleaning work is completed.

Next, when the ultrasonic cleaning is finished, first, the lid 51 of the rinsing tank 3 is opened and the cleaning basket 5 is manually operated by the ultrasonic cleaning tank 2.
Then, it is placed on the rotary table 28 in the rinsing tank 3, and the positioning boss (not shown) of the cleaning basket 5 is fitted into the positioning holes 33, 33 ... After that, the lid 51 is closed and the rinsing / cleaning start switch on the operation panel 52 is turned “ON”, and the rinsing / cleaning proceeds in the step shown in FIG.

That is, the liquid supply valve 35 is opened, and the cleaning liquid high temperature pipe 2
The high temperature water from 0 and the normal temperature from the cleaning liquid normal temperature pipe 18 are mixed to supply the rinsing liquid which is the proper temperature water. In the meantime, the reversible motor 29 causes the turntable 28 to rotate in the forward and reverse directions to rotate the cleaning basket 5 in the forward and reverse directions. When the specified amount of the rinse liquid is supplied, the liquid supply valve 35 is closed and the waste liquid valve 37 is opened, and at the same time, the forced waste liquid pump 39 is operated to perform rapid drainage. When the cleaning basket 5 rotates while the rinsing liquid is in the rinsing tank 3, a part of the rinsing liquid rises due to the stirring pieces 34, and the rinsing liquid flows in the center of the cleaning basket 5 to improve the rinsing effect. Let

The rinsing work is performed by repeating the supply of the rinsing liquid and the waste water, but when a predetermined time elapses,
The liquid supply valve 35 is closed, the waste liquid valve 37 is opened, the forced waste liquid pump 39 is turned “ON”, and rapid drainage is performed. At this time, the drain valve 49 is opened to drain the rinse liquid accumulated in the hot air pipe 46. During this time, the rotary table 28 repeats normal and reverse rotations.

When the rinsing liquid in the rinsing tank 3 is discharged, the hot air blower 48 is turned "ON", air is taken in, the air is sent to the hot air generator 47, and it is turned into hot air and provided in the rinsing tank 3. Hot air is blown from the hot air blowing port 45 to the cleaning basket 5 to perform hot air drying. At this time as well, since the cleaning basket 5 is rotating in the normal and reverse directions, the water droplets attached by the centrifugal force are scattered to improve the drying effect. When the drying for the specified time is completed, the rotary table 28 is stopped. Then, the lid 51 is opened and the cleaning basket 5 is taken out.
